Do a slab of n type material carry a net negative charge?
No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).
What is a type of material that let's heat flow through it easily?
metal
What m is a type of material that let's heat flow through it easily?
metal
What are two factors that determine how easily water can move through materials?
Two Factors are the type of material. The best material water moves through is a partially permeable membrane. Another factor is the substances dissolved in the water and the substances inside the material. There can also be if there are pores that are connected.
What is a material that energy can transfer through easily called?
Depends on what type of energy, but usually they are called conductors.
In what type of material do electrons move easily?
Metal, I think.
In what type of material do electrons move easily in?
Metal, I think.
What type electrically charged particles move from one material to another more easily?
Electrons.
What type of material allows electrons to move freely?
Electrons move freely in a solid, as in a metal
Do a slab of n type material carry a net negative charge?
No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).
Something electrons cannot move through easily?
Electrons cannot easily move through a type of material called electrical insulators. These materials tend to be plastics or rubber. Just think of the coating on wires in your home for example
Which direction do electrons move in when metals react with non metals?
During this type of reaction, the electrons would move from the metal to the non-metal. The transfer of electrons allows both material to maintain a full outer valence.
How many valance electrons does a semiconductor have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
What causes the electrons to move in a solar panel and how?
Electrons move in a solar panel because of something called the photoelectric effect. Light, such as from the sun is made up of photons. When a photon strikes a metal, it knocks lose electrons. This effect can vary based on the type of metal. Solar panels are designed to allow electrons to be easily effected.
What m material is a type of material that lets heat through it easily?
metal
What is an n-type semiconductor?
An n-type semiconductor is a type of material that has been doped with impurities to increase the number of free electrons, giving it a negative charge. This excess of electrons allows the material to conduct electricity more easily. N-type semiconductors are commonly used in electronic devices due to their ability to carry current.
What is the net charge on a n-type or a p-type substance?
There is no net charge on either substance. However, an N type substrate contains atoms (such as arsenic or phosphorous) trapped in its lattice that have an electron (called a donor electron) in the outer (valence) band of electrons, which can be easily removed by a relatively weak electromotive force (voltage). A P type substrate, although electrically neutral, contains an element (such as boron) which has one fewer electrons in its valence band that it would like to have, making it an acceptor. The missing electron is often called a "hole". To elaborate slightly, bands of electrons like to have a certain number of electrons to be "stable". A donor atom may have one, or perhaps five, electrons in its valence band, while an acceptor might have three or seven. Both would be happier with zero or four or eight. When an N and a P type substance are in contact, a negative voltage on the N material with respect to the P material will allow electrons to move from the donor material to the vacant holes in the acceptor. If the voltage is applied in reverse, the negative charge on the P material attracts the holes away from the junction, and the (relatively) positive charge on the N material attracts electrons away from the junction, and very little current flows.
